Hi @Larry Lehman ,
Welcome to Microsoft Q&A forum.
I checked on my side, with the latest version of VS 2022(17.4.4), tested in WinForm and WPF projects(.NET 6 and .NET 7), but the toolbox showed controls correctly.
Please try following suggestions, if the toolbox still doesn’t show the controls, please kindly report this issue on our Developer Community(in VS => click Help => Send Feedback => Report a Problem…).
- Try to double click the Form.cs file/MainWindow.xaml file and check if the toolbox shows the controls.
- Try to right-click the white space of the Toolbox windows => click Reset Toolbox.
- Try to open VS Installer => More => Repair => reboot your machine => restart VS.
- If it is acceptable, try to uninstall and reinstall VS 2022.
Best Regards,
Tianyu
